采用双轴和三轴晶体谱仪测试了三种测量方法：(1)分析仪扫描法（AS），(2)单色仪扫描法（MS）和(3)单色仪扫描法（MAS）。建立了一个高压电池，主要用于粉末衍射测量，散射角为30、60、90和120，样品体积约为0.8 cm，并与MS和MAS方法结合使用。在室温下，这种电池可以在高达约40千巴的压力下进行测量，在300℃下可达到约30千巴的压力。报告包括衍射方法和高压电池的描述。文中还给出了一些实验结果。
Three potider measurements using double- and triple-axis crystal spec trometers were tested: (1) the analyzer-scan method (AS), (2) the monochromator-scan method (MS), and (3) the monochromator-analyzer scan method (MAS). A high-pressure cell, primarily for use in powder diffraction measurements, with scattering angles of 30 , 60 , 90 and 120 and a sample volume of about 0.8 cm was constructed and used in conjunction with the MS and MAS methods. At room temperature, this cell makes it possible to make measurements at pressures up to about 40 kbar and up to about 30 kbar at 300° C. The report includes a description of the diffraction methods and of the high-pressure cell. A few examples of experimental results are also given.
